Descripción detallada

El CS125 utiliza el conocido sistema de dispersión (scattering) de 42º para la medición de la visibilidad, que ofrece estimaciones precisas de Meteorological Observable Range (M.O.R.) para niebla y nieve.

En él se identifican las partículas de precipitación de sus propiedades de dispersión y las velocidades de caída, y combina los datos con una medición de temperatura para poder identificar el tipo de clima. Se ha apuntado hacia abajo la óptica para reducir el riesgo de contaminación de las lentes y el bloqueo por nieve.
La interferencia con el volumen de la muestra del sensor por la distorsión de flujo o de calor se reduce al mínimo.

También proporciona información sobre el tiempo presente fiable en forma de códigos SYNOP incluida la información sobre la intensidad de la precipitación. También puede ser reportado el valor de la precipitación.

El CS125 utiliza el muestreo continuo de alta velocidad para reducir errores durante fenómenos meteorológicos mixtos y eventos que devuelven señales intermitentes, como la lluvia y el granizo, mientras que todavía proporciona lecturas fiables durante los eventos más estables, como la niebla y la niebla. El CS125 tiene una alta inmunidad a la interferencia de las luces de advertencia visibles e infrarrojas utilizadas para marcar obstáculos, como en las turbinas eólicas de los aerogeneradores.

El CS125 incorpora calentadores para poder prevenir el efecto de la condensación en las lentes y de serie también calentadores anti heladas de alta potencia. Estos calentadores se controlan automáticamente para poder asegurar el funcionamiento en todas las épocas, o se pueden desactivar de forma individual para ahorrar energía.

El CS125 supervisa continuamente su propio estado y reportará los fallos internos y la contaminación o bloqueo de las lentes de los sensores. También cuenta con dos salidas de alarma configurables por el usuario que se pueden utilizar para activar alarmas sonoras o visuales que utilizan relés de estado sólido.

Sensor certificado por la agencia Meteorológica de Alemania (Deutscher Wetterdienst) como adecuado para su uso en el control de los sistemas de luz de obstrucción de aerogenerador según las especificaciones 506/04 (General Administrative Rules for the Identification of aircraft Obstructions).

CR1000X CS125 example programs v.1 (10 KB) 18-03-2020

CR1000X programs that read continuous data and polled data and use the SET, SETNC, and GET commands. The program that uses the SETNC command powers the CS125 hood heaters when needed according to the dew point. A HydroVUE5 Air Temperature and Relative Humidity Sensor provides the measurements used in the dew point calculation.


CS125 and CS120A OS v.13 (156kb) 22-11-2019

Campbell Scientific has introduced a new operating system, OS13, for the CS120A visibility sensor and CS125 present weather sensor. It is fully backwards compatible and is easily installed on all CS120A and CS125 sensors (but not older CS120 sensors). OS13 is available free of charge and can be downloaded here or supplied by email on request.

Upgrade to OS 13 is recommended.

Changes to both CS120A and CS125

To optimise user calibrations, OS13 temporarily disables hood heaters during calibration and resumes normal hood functionality once the calibration is complete.

Hood heaters now operate down to the fault alarm levels of -56°C, but will turn off at low temperatures if a thermistor fault is detected.

OS13 better flags DC saturation, which under very bright conditions might occasionally produce a dirty lens alarm.

OS13 has corrected the potential for level 1 dirty window alarms to occur during heavy fog and rain where visibility drops below 10m.

Changes to CS125 only

OS13 contains improved filtering to reduce the occurrence of short duration precipitation reports caused by transient insect activity. The sensor still retains its sensitivity to the detection of precipitation. 

Automatic optimisation to differing background light levels reduce the occurrence of erroneous particles reported in bright light.

OS13 includes a software switch to turn off BCFG from the CS125 message output. If triggered by broken fog, the BCFG message could affect AWOS systems. This does not affect the CS120A.
